Fig. 4.

Transmission electron microscopy of psp+ (AJD3) and Δpsp (AJD1171) cells containing pVLT35 (− YscC) or pAJD126 (+ YscC). Samples were grown for 3 hr with 200 μM IPTG. Arrows point to areas of apparent cell envelope layer separation that resembles a plasmolysis phenotype. Bars in the lower left hand corner of each panel represent 500 nm.
